Recommended Action
Introduce an ordinance amending Section 10.28.325 and adding Sections 10.28.154, 10.28.155
and 10.28.156 of the Carlsbad Municipal Code to establish all-way stop control at the
intersections of Batiquitos Drive and Aviara Drive and at La Costa Avenue and Camino De Los
Coches.
Executive Summary
Staff evaluated the intersections of Batiquitos Drive and Aviara Drive and at La Costa Avenue
and Camino De Los Coches for all-way stop signs in response to requests from the community
and as part of the city’s ongoing efforts to improve traffic safety.
The evaluation was conducted in accordance with the California Manual on Uniform Traffic
Control Devices, which serves as the standard and guidance document for traffic control
devices installed in the State of California, including traffic signs, road surface markings and
traffic signals.
Based on this analysis, the intersections satisfy the criteria for all-way stop consideration.
On May 4, 2026, the Traffic Safety & Mobility Commission voted to approve staff’s
recommendation to the City Council to establish all-way stop control at the intersections of
Batiquitos Drive and Aviara Drive and at La Costa Avenue and Camino De Los Coches.
Staff are asking the City Council to introduce an ordinance to amend the Carlsbad Municipal
Code to establish all-way stop control at these intersections. Only the City Council has the
authority to make changes to the Carlsbad Municipal Code.

Explanation & Analysis
Multi-Way Stop Analysis
An all-way stop analysis, in accordance with the guidelines found in the Manual on Uniform
Traffic Control Devices, considers vehicle, pedestrian and bike volumes as well as other factors
such as collision history, sight distance, movement conflicts and traffic operations to determine
whether all-way stop control is justified at a particular intersection. The analysis conducted by
staff is structured around the following four primary criteria and four other criteria in the
manual:
•Criterion A allows consideration of a multi-way stop as an interim measure prior to
installation of a traffic signal.
•Criterion B allows for consideration of a multi-way stop when there have been five or
more reported collisions within a 12-month period that are susceptible to correction by
a multi-way stop.
•Criterion C evaluates the traffic volumes to determine if a multi-way stop can be
considered. Criterion C is satisfied if:
1)The vehicle volume entering the intersection from the major street, total of both
approaches averages at least 300 vehicles per hour for any eight hours of an average
day
2)The combined vehicular, pedestrian and bicycle volumes entering the intersection
from the minor street, averages at least 200 units per hour for the same eight hours
with an average delay to minor street vehicular traffic of at least 30 seconds per
vehicle during the highest hour
3)If the 85th-percentile approach speed of the major-street traffic exceeds 40 miles
per hour, or mph, the minimum vehicular volume thresholds are 70% of the values
provided in Parts 1 and 2. (The 85th-percentile speed is the speed at or below which
85% of drivers naturally travel under free-flowing conditions. It is used to gauge the
safe and reasonable operating speed of a roadway.)
•Criterion D allows consideration of a multi-way stop where no single criterion is satisfied
but where Criteria B and C are satisfied to 80% of the minimum values.
Other Criteria
In addition to the four criteria listed above, the Manual on Uniform Traffic Control Devices
provides other criteria that may also be considered. The other criteria are described as:
A.The need to control left-turn conflicts;
B.The need to control vehicle/pedestrian conflicts near locations that generate high
pedestrian volumes;
C.Locations where a road user, after stopping, cannot see conflicting traffic and is not able
to negotiate the intersection unless conflicting cross traffic is also required to stop; and
D.An intersection of two residential neighborhood collector (through) streets of similar
design and operating characteristics where all-way stop control would improve traffic
operational characteristics of the intersection.

Analysis results
Staff evaluated the subject intersections in accordance with the guidelines mentioned above.
Based on the analysis, each of these locations meets at least one of the criteria for all-way stop
consideration.
Batiquitos Drive and Aviara Drive
None of the primary criteria were met for this intersection, but the other criteria B was met.
A — Interim measure: No
B — Collision history: No
C — Traffic volumes: No
D — Satisfy 80% of criteria: No
Other — B : Yes
La Costa Avenue and Camino De Los Coches
This intersection met one primary criterion — traffic volumes, and the other criteria B.
A — Interim measure: No
B — Collision history: No
C — Traffic volumes: Yes
D — Satisfy 80% of criteria: No
Other — B: Yes
The Manual on Uniform Traffic Control Devices worksheets for each of the intersections studied
are provided in Exhibits 3 and 4. The following sections provide further explanation for the
criteria satisfied at each intersection.
Intersection of Batiquitos Drive and Aviara Drive
Batiquitos Drive and Aviara Drive are both
classified as local/neighboring streets in the
General Plan Mobility Element, the element
that covers transportation, and are located
within the southwest quadrant of the city,
as shown in the location map provided as
Exhibit 6. Batiquitos Drive is a two-lane
road with a striped median and has a curb-
to-curb width of approximately 46 feet.
Bike lanes are provided on both sides of
Batiquitos Drive and on-street parking is
not permitted. It has a posted speed limit of
40 mph. This segment of Batiquitos Drive
runs in an east–west direction. There is an uncontrolled marked crosswalk enhanced with
rectangular rapid flashing beacons – pedestrian-activated warning devices installed at
June 23, 2026 Item #11 Page 3 of 20
unsignalized crosswalks – crossing Batiquitos Drive on the west leg of the intersection for
pedestrians accessing the Aviara Golf Club and the Batiquitos Lagoon trail to the south.
Aviara Drive is a two-lane roadway with parking permitted in both directions. It has a curb-to-
curb width of approximately 40 feet. Aviara Drive runs in a north-south direction terminating at
Batiquitos Drive where it meets the driveway for the Aviara Golf Club. Both Aviara Drive and the
golf club driveway are controlled by a stop sign at this intersection.
City staff received concerns regarding speeding and safety at this intersection, along with
requests to install all-way stop control. In response to these requests, traffic data were
collected for an all-way stop analysis on Feb. 4, 2026. The collected counts indicate that 221
pedestrians crossed at the intersection over the course of a typical day. With access to the trail
and the Aviara Golf Club, implementing an all-way stop control is expected to reduce conflicts
and enhance safety by clarifying who has the right-of-way and providing consistent crossing
opportunities for pedestrians at this intersection, satisfying the Other Criterion B. Staff
therefore recommend implementing an all-way stop control at the intersection of Batiquitos
Drive and Aviara Drive.
With the installation of an all-way stop control, high-visibility crosswalk markings will be
installed at all legs of the intersection. The existing rapid flashing beacons for the existing
uncontrolled crosswalk will be removed because they are warning devices and are not allowed
at stop-controlled crosswalk locations under the Manual on Uniform Traffic Control Devices.
Intersection of La Costa Avenue and Camino De Los Coches
La Costa Avenue and Camino De Los
Coches are both classified as
neighborhood connector streets in the
General Plan Mobility Element and are
located within the city’s southeast
quadrant, as shown in Exhibit 6. La Costa
Avenue runs in an east–west direction,
and Camino De Los Coches intersects it at
a T-intersection currently controlled by a
stop sign.
West of Camino De Los Coches, La Costa
Avenue is a four-lane road with a striped
median and has a curb-to-curb width of
approximately 64 feet. East of the intersection, between Camino De Los Coches and Circulo
Sequoia, it’s a two-lane road with an intermittent raised median. It has a curb-to-curb width
ranging from approximately 40 feet to 64 feet. The posted speed limit is 45 mph west of
Camino De Los Coches and reduces to 35 mph east of the intersection. The 85th-percentile
speeds on La Costa Avenue were 45 mph eastbound and 42 mph westbound. Bike lanes are
provided on both sides of La Costa Avenue, and on-street parking is not permitted.
Camino De Los Coches is a two-lane roadway with a striped median. It has a consistent roadway
width of 64 feet and a posted speed limit of 40 mph. Bike lanes are also provided on both sides
of Camino De Los Coches, and on-street parking is not permitted.
June 23, 2026 Item #11 Page 4 of 20
City staff have received concerns regarding pedestrian safety and vehicle speeds at this
intersection, along with requests for an all-way stop control. In response to these requests,
staff collected traffic data for the all-way stop analysis on Aug. 23, 2025.
Based on the data collected, traffic volumes on both La Costa Avenue and Camino De Los
Coches met the volume thresholds for roadways with measured speeds above 40 mph, thereby
satisfying Criterion C for all-way stop consideration.
Additionally, this intersection is close to the La Costa Town Square, La Costa Canyon High
School, Stagecoach Community Park and a church, which are facilities that generate high
bicyclist and pedestrian activities. Traffic counts indicate that 115 bicyclists and 252 pedestrians
used the intersection over the course of a typical day. Implementing all-way stop control is
expected to reduce conflicts and enhance safety by clarifying right-of-way and providing
consistent crossing opportunities for pedestrians at this intersection, thereby satisfying Other
Criterion B.
Based on these findings, staff recommend installation of all-way stop control at the intersection
of La Costa Avenue and Camino De Los Coches.
High-visibility crosswalk markings on Camino De Los Coches will be installed at the same time
that the stop signs are installed. Crosswalk markings for crossing La Costa Avenue will be
installed later when new pedestrian ramps are installed on the north side of La Costa Avenue as
part of a future Capital Improvement Program project.
Community outreach
Staff have notified affected residents, business owners and others who may be interested in the
installation of an all-way stop control at the three intersections.
•Doorhangers to residents and property owners adjacent to the intersections
•Email to the property management company of apartments in the vicinity
•City Manager’s Update e-newsletter
•Updates on Nextdoor
Traffic Safety & Mobility Commission recommendation
Staff’s recommendations to install all-way stop control at the two intersections were presented
to the Traffic Safety & Mobility Commission on May 4, 2026.
The commission supported staff’s recommendation to install an all-way stop control at the
intersections of Batiquitos Drive and Aviara Drive and at La Costa Avenue and Camino De Los
Coches.
The approved meeting minutes from this meeting are provided as Exhibit 5.
June 23, 2026 Item #11 Page 5 of 20
Fiscal Analysis
The total estimated cost to implement all-way stop control at the three intersections is
approximately $16,000. Sufficient funds are available in the Traffic Engineering Operating
Budget to cover the proposed work.
Estimated cost breakdown by location
Intersection and associated beacons Total
Batiquitos Drive and Aviara Drive $7,000 $3,000 $10,000
La Costa Avenue and Camino De Los
Coches $6,000 — $6,000
Next Steps
Following the City Council’s introduction of the ordinance, the ordinance will be scheduled for
adoption at the City Council’s next meeting. The ordinance will then become effective 30 days
following adoption.
After the ordinance goes into effect, staff will move forward with the installation of stop signs
and associated pavement markings at these intersections. The existing rapid flashing beacons
on Batiquitos Drive near the Aviara Drive intersection will be removed concurrently with the
installation of all-way stop control.
Environmental Evaluation
The proposed action to establish all-way stop control and associated roadway striping is
categorically exempt from environmental review under California Environmental Quality Act, or
CEQA, Guidelines Section 15301(c) because it involves the maintenance, repair or minor
alteration of existing facilities with negligible or no expansion of the existing or former use. This
exemption covers changes in traffic and parking regulations, including installation and
replacement of related signs where such changes do not establish a higher speed limit along a
significant portion of the street and will not result in more than a negligible increase in use of
the street. No exceptions to the categorical exemption as set forth in CEQA Guidelines Section
15300.2 or Carlsbad Municipal Code Section 19.04.070(C) apply.
The proposed action is also exempt from the requirements of a minor coastal development
permit and coastal development permit because the proposed action is to establish all-way
stop control. Activities of public utilities as specified in the repair, maintenance, and utility
hookup exclusion adopted by the Coastal Commission, including but not limited to
miscellaneous traffic safety projects, are exempt in accordance with Carlsbad Municipal Code
Section 21.201.060.B.11. A permit issued by the city for a development which is categorically
excluded or exempt from the coastal development permit requirements is exempt from the
notice and hearing requirements of Carlsbad Municipal Code Chapter 21.201.
The proposed action to adopt an ordinance amending Sections 10.28.325 and adding Sections
10.28.154, 10.28.155 and 10.28.156 of the Carlsbad Municipal Code to establish all-way stop
control at the intersections of Batiquitos Drive and Aviara Drive and at La Costa Avenue and
June 23, 2026 Item #11 Page 6 of 20
Camino De Los Coches is also exempt from environmental review under CEQA Guidelines
Sections 15061(b)(3) and 15378(b)(5) because it can be seen with certainty that there is no
possibility that the proposed action may have a significant effect on the environment.

Subject:Proposed four-way stop at intersection of La Costa and Camino de Los coches
To whom it may concern,
I am a homeowner just east of the intersection referenced above and do not feel that a proposed three-
way stop is necessary. Perhaps a flashing stop that is triggered when cars are turning east or west from
Camino de Los Coches is a more reasonable solution but a permanent 3 way is not necessary. The new
proposed stop is too close to the one just east of this intersection and the one to the west.
Thank you for taking this into consideration. I’m not able to attend the City meeting.
If you have any questions, please let me know. Sincerely.

Subject:Proposed four-way stop at La Costa Avenue and Camino de los Coches
As a resident of the La Costa Oaks neighborhood that uses that intersec on on a daily basis, though I am hesitant to
impede the pace of my own commute, I realize the danger of that intersec on and have almost had a few few accidents
there myself given the traffic associated with local high school school students. I presume that this change would
significantly improve the safety associated with that intersec on and probably improve the flow of traffic when the high
school is in and out of session.
Sincerely,
Sco Sporrer

Subject:proposed all-way stop at the intersection of La Costa Avenue and Camino De Los Coches
Date:Wednesday, June 17, 2026 5:38:47 PM
Regarding a proposed all-way stop at the intersection of La Costa Avenue and
Camino De Los Coches:
I don’t think this is necessary for the brief times around school hours when this
intersection becomes busy.
The noise and additional pollution caused by cars having to stop on La Costa Avenue
when the is no traffic on Camino De Los Coches will be more disruptive.

Subject:Proposed All Way Stop
Date:Wednesday, June 17, 2026 8:02:02 PM
Hi,
My name is Dan Williams and I live in the La Costa Oaks area just off of RSF and Avenida Soledad. I read about
the upcoming discussion about putting in a four way stop sign at Camino De Los Coches and La Costa Avenue and I
wanted to email my support for it. Our kids are going to start going to La Costa Canyon hight school and riding
their bikes to LCC and that intersection is on thier way to school. I have seen cars driving incredibly fast down that
road, both straight and turning on to Camino De Los Coches from La Costa at high speeds. It’s dangerous for those
cars to be traveling fast with kids riding thier bikes to school. I think a four way stop sign would dramatically help
reduce those speeds and increase safety.
I hope you all vote in favor of adding a four way stop sight toCamino De Los Coches and La Costa Avenue.
Thank you
Dan Williams

Dear City Council:
I live in the La Costa Oaks neighborhood and am opposed to the proposed all-way stop at La
Costa Ave and Camino de los Coches. It increasingly difficult to navigate our neighborhoodand adding more stop signs will only create more congestion, more impatient drivers and more
danger.
Please do NOT approve this stop sign. If you'd like more information, feel free to contact me.
Thank you,

To whom it may concern,
I am a resident of La Costa Oaks south. I cannot attend the council meeting on Tuesday, so Iam sharing my support of all-way stops at La Costa and Camino De Los Coaches via email.
I have encountered many near-accidents at that intersection, the latest as recent as last week. I
was driving eastbound on La Costa and a car failed to yield to my right-of-way and turned leftfrom Coaches onto La Costa in front of me. I was able to brake and swerve to avoid collision
but twas deeply upset since I had my three children in the car.
Thank you for taking my experience into consideration as the city makes their decision.
Sincerely,Katherine E. Kincaid

Subject:4-way stop signs on Aviara Drive, and Batiquitos.
Date:Monday, June 22, 2026 3:06:36 PM
Please don't do. It is not only totally unnecessary , it is frustrating to make drivesr stop for no
reason, and I do mean no reason. Ipass this area all the l time. tmight give some small benefittothose coming out of the golf course parking lot or Aviara drive, but is a waste of fuel; stop
starts cause pollution. I looked at d this from all 4 sides. I just don't need the reason for it. tImight give some small benefit to a small number of of drivers to the irritation of those on
Batiquitos like myself.. Carlsbad used to be a rather conservative, level-mindedg city, andnow seems to b more and more taken over b yrhe radical fringe. Why they are doing this I just
don't understand. It is a sad situation.Take a beautiful street and ruin it with unnecessary stopsigns.
By the way, I use intersection daily where Kestral and Batiquitos cross. Should we put 4stop signs there? . Kestrel has more traffic than that coming out of the Golf course parking
lot. So, once again, why are you doing this ?
Regards,Daniel Boilini
